Filterless Snapshot Hyperspectral Imaging using Guided Patch Diffusion
Dean Hazineh, Luca Sacchi, Davide Cassara +2
We consider the problem of reconstructing a HxWx31 hyperspectral image from a grayscale snapshot measurement that is captured using only a single diffractive lens and a…

Antireflection by design in bilayer metasurfaces
Jaewon Oh, Davide Cassara, Alfonso Palmieri +5
Antireflection coatings are ubiquitous in optical systems, where they maximize transmission and suppress undesirable reflections by impedance-matching uniform interfaces. Extending…

Topology-Optimized Dielectric Cavities for Enhanced Excitonic Light Emission from
Owen Matthiessen, Brandon Triplett, Omer Yesilyurt +14
Photonic inverse design and, especially, topology optimization, enable dielectric cavities with deeply sub-diffraction mode volumes and high quality factors, thus offering a powerf…
